Leave.eu, the Brexit campaign group co-founded by Aaron Banks have been accused of indulging in anti-Semitism, after tweeting a comment from a Tory Brexiteer MP with an image of George Soros, the pro-remain billionaire financier.

The organisation, which campaigned for the UK to leave the EU during the lead up to the 2016 referendum, published the controversial tweet in which they warn “there's a concerted effort to thwart the will of the people.”

17.4m people voted leave the European Union. More than two years later we're still in the EU and there's a concerted effort to thwart the will of the people. If Brexit is not delivered, we can no longer pretend we're living in a democracy...

Attached to the tweet is an image of Maria Caulfield, beside a ghost-like image of George Soros, and a quote from the MP, reading: “...the powerful elite seem to know best and openly mock the rest of us.”

Caulfield claims Leave.eu did not ask for her permission to publish her words and has called on the group to delete the tweet, revealing in a subsequent tweet that it was particularly hurtful “as my family are Jewish.”

The organization’s tweet has been picked up by Henry Newman, Director of Open Europe, a liberal pan-European think tank who described the image as shocking, labeling it “nakedly anti-Semitic.” There have been claims on social media that the obsession with Soros played into anti-Semitic stereotypes of rich Jews “controlling” society.'

Flashback - May 2018: Billionaire George Soros Is Backing a Massive Campaign for a Second Brexit Vote. But Does It Stand a Chance?

'Brexit won’t happen if billionaire philanthropist George Soros has anything to say about it.

Soros announced Tuesday that Best For Britain, a campaign to secure a second referendum on whether the U.K. should leave the EU, will launch its ‘manifesto’ on June 8. The manifesto will reportedly include a roadmap for stopping Brexit.

The campaign, which was created by Gina Miller last year, has already received millions of pounds in donations according to The Guardian, including £500,000 (approx. $663,000) from Soros. It aims to persuade members of parliament to require a new referendum on the final withdrawal deal. In order to do so, it will focus on engaging with voters, and Brussels as well.

In a speech at the European Council on Foreign Relations, a think tank Soros helped found, the billionaire said that “Best for Britain fought for, and helped to win, a meaningful parliamentary vote which includes the option of not leaving at all.”

“But the British public must express its support by a convincing margin in order to be taken seriously by Europe. That’s what the Best for Britain is aiming for by engaging the electorate,” he continued.

Soros explained that “Brexit is an immensely damaging process, harmful to both sides.” While he acknowledged that “it’s up to the British people to decide what they want to do,” he pointed out that “it would be better…if they came to a decision sooner rather than later.”

Despite supporting the U.K. remaining in the EU, Soros did concede that the EU is facing “an existential crisis,” due in no small part to the ongoing political crisis in Italy. He therefore argued that “the EU needs to transform itself into an association which nations like Britain would want to join.”'
